Biographical Sketch

Prof. Rothberg received his B.S. in Physics (1977) from the University of Rochester and his Ph.D. in Physics (1984) from Harvard University. He then worked at Bell Laboratories until 1996, rising to the position of Distinguished Member of Technical Staff. Prof. Rothberg joined the University as Professor of Chemistry in 1996 and currently has joint appointments in Chemical Engineering and Physics. Rothberg received the AT&T Bell Labs Global Mfg. & Eng. Teaming Excellence Award in 1995 and was named Fellow of American Physical Society in 1996.

Research

Prof. Rothberg≠s interests are in the general areas of experimental Chemical, Biological and Condensed Matter Physics. His group carries out research in three main areas. One of these is understanding molecular electronic materials with an eye to elucidating the physics necessary to use these for light-emitting display technology, organic solar cells and electrooptic switching. This work includes collaborative studies with Eastman Kodak, Prof. Chen in Chemical Engineering and Prof. Galvin at the University of Delaware. The second area involves fundamental studies of the enhancement of optical properties by metal nanoparticle plasmon resonance. These include single molecule Raman and fluorescence spectroscopy as well as nonlinear optics. Finally, the group has several projects in biomolecular sensing and develops new assays that are useful for clinical and research applications. These are based on optical or electrical detection of small quantities of unmodified oligonucleotides or important proteins. Each of these projects is in collaboration with personnel at the Medical School.
